0 = f(x) = (x - r)(x - s) = x² - (r+s) + rs
We have r=1.5+√2, s=1.5 -√2 so r+s = 3 and
rs = (1.5+√2)(1.5 - √2) = 1.5² - (√2)² = 2.25 - 2 = 0.25
f(x) = x² - 3x + -.25
For integer coefficients we mulitply by 4,
g(x) = 4f(x) = 4x² - 12x - 1
Answer: 4x² - 12x - 1 = 0

Answer:
Step-by-step explanation:
Add them all together to get your answer
D 18 and must be a positive number
Answer: (-5,-3)
Step-by-step explanation:
first you must know left and right is the x-axis while you and down is 4-axis, down and left is subtraction, right and up is addition
so 3 units left would affect x axis therefor subtracting 3 from -2 which is -5
now 5 units down would be the y-axis and subtracting, 2-5= -3
finally your answer will be (-5,-3)
